Trend Watch: Celebrities in Masks

2 Chainz played a show in Detroit's Fox Theater last night in what is reportedly a Chanel ski mask. While Kanye West has drawn attention to the masks he wears onstage and at fashion shows, A$AP Rocky has also been spotted covering his face and more recently, Justin Bieber, who inexplicably wore a gas mask while shopping in London—although we came up with a few situations it might come in handy.

French Montana had been spotted in what's probably a Versace ski mask as early as October, with Rocky wearing a bright orange one onstage during concerts that month as well. Is this a winter time trend or are these celebrities just trying to keep their faces warm?
